Objectives and Strategy of TC 100
Two major objectives of TC 100 standardization are:
 to enrich human life with entertainment provided by
audio, video and multimedia in home and networked
environment; and
 to contribute to society by pursuing energy efficiency
and by addressing the options for accessibility in the
use of audio, video and multimedia equipment.

Accessibility
TC 100 recognizes accessibility as one of AAL topics
In 2007, TC 100/AGS recognized the need of
investigation for accessibility standardization and
established a Stage 0 project to produce a Technical
Report (published in 2010）
 IEC TR 62678: Audio, video and multimedia systems and
equipment activities and considerations related to accessibility and
usability
- Downloadable free of charge from IEC Web store
TC 100 is developing a “text-to-speech” standard
 IEC 62731: Text-to-Speech Functionality for Television - General
requirements
(CDV stage, 18 May 2012)

TC 100 consideration for AAL
TC 100/AGS is discussing AAL as one of new
themes for the future
 3DTV
 AAL (Ambient Assisted Living）
Liaison with European Blind Union (EBU)
Formed SG 5 Task Group in AGS
 Smart Grid and energy efficiency, DC distribution
 EV and multimedia

AAL Challenge
 Develop systems, devices and interfaces that older
people can use comfortably, intuitively and
independently in their homes
 Not to feel being watched
 Monitor people's health, keep their homes secure
and help them stay fit and connected with family
and friends
 Overcome barriers to the acceptance and usability
of AAL systems through innovative user-centric
design and accessibility needs of elderly and
disabled people

Barriers to Accessible Solutions
Solutions
Visual impairments
Design mainstream ICT products / services so that the visual
presentation can be adjusted by the users (e.g. displays with
adjustable font size, contrast, use of colours)
Design ICT products/services so
that they are compatible with
assistive technologies for blind
users such as text-to-speech
software
Ensure that audio outputs are adjustable in sound volume & quality
Provide audio & other output modes as alternative
(e.g. vibrating) to audio signals
Barriers
Provide speech, audio and other output
modes as alternative to visual displays
& status indicators on ICT products
Provide second audio channel / track
to narrate the visual component of
TV broadcasts / videos
Hearing impairments
Cannot read visual
Provide text captions enabling deaf people
Cannot hear
displays
to follow the audio component of
voice on telephone
TV broadcasts / videos
Cannot see visual
Cannot hear audio
system status signals
status signals
Provide text telephones & operator relay
Cannot see
services enabling text phone users to
Mobile
phones
visual web
communicate with voice phone users
interfere
with
content
hearing aids
Cannot watch
TV broadcasts
Cannot hear
TV audio
Online content
too difficult to
understand
(e.g. complex
language)
Design online services and other
ICT-based products so that they
are understandable and usable by
people with cognitive impartment
(e.g. simple/consistent menu structure,
consistent use of icons , easy language)
Public
terminals
unreachable
in wheelchair
Interfaces
requiring too fine
manipulation
skills
Cannot talk to voice-based
services & systems such as
call centres & interactive
response services
Interface / menu
too complex
to use
Design online services and other ICT-based
products to accommodate age related
changes in information processing capabilities
(e.g. lower reaction speed, less fine motor
skills, reduced memory capacity)
Provide alternative to speech input in
interactive voice systems
Design mobile phones to minimise
interferences with hearing aids
Design public telephones, ticket
machines, information kiosks,
cash dispensers so that they are
accessible to wheel chair drivers
Design key pats, touch screens
and other interfaces to cater for people
with dexterity problems (e.g. less sensitive,
better spaced, larger buttons)
Design ICT products/services so that
they are compatible with assistive
technologies for people with dexterity
impairments (e.g. alternative input devices)
Provide text telephones & operator relay
services enabling text phone users to communicate with
voice phone users
Cognitive impairments
Speech impairments
Physical &
mobility impairments

Proposed Way Forward for TC100
 Define use case for standardisation
 Example: Barriers to Smart TV take up
 Use cases are the basis for further development of
standards in the following areas
– Terminology
– Technical requirements
– Interoperability
– Standard Gap Analysis

Use Case: Smart TV (1) (Guido Gybels, EBU)
 Barrier to current Smart TV uptake is the home networking and UI usability
 For example, even though about 25% of UK households now have a
Smart TV with an iPlayer in it compared to about 11% of households who
have iPlayers on a tablet, the consumption of BBC content through the
tablet version is 4 times as high as on a Smart TV
 This indicated that many people don't actually connect their smart TVs to a
network.
 There is scope for both use case and guidelines work to define the
requirements and functionality for easy home networking - setting up and
using a device. The complexity of IP home network setup is quite a barrier
for many people.
 Because quite a lot of AAL activities focus on medical/well-being and
monitoring, there must be scope for the role of Smart TVs and definition of
a common framework and an application environment to deliver e.g.
medical services via a return path of a connected TV and other consumer
equipment.

Use Case: Smart TV (2) (Guido Gybels, EBU)
 The external connectivity of Smart TVs offers a great opportunity to deliver
external accessibility solutions by means of applications running on tablets
and the like and allowing for instance a blind user to operate their TV
through a TTS based smartphone or tablet app, but also elderly people
with diminished sight and perhaps dexterity problems to control their TV
with a more accesible remote control app on a tablet.
 You could also deliver additional content. Manufacturers already have
some remote apps but these aren't designed for accessibility and because
there is no agreed standard for control in this way that external access
technologies could use, there is an interoperability problem for such
applications as well as a problem of interfaces/functionality.
 For instance, it is no good to have an external control API that, say, an
application for blind people could use to offer an external speaking solution
if the API has no function to turn on/off the AD.
